IDC Design · Style Library Report

Style Library × the last 30 days

What people in the UK & US are actually posting about interior design right now — mapped against the IDC style library (now 26 styles). What we cover, what we partly cover, and where the gaps are.

What the research found

A deep pull across social, video and the design press for the window . The signal splits cleanly in two: a designer-taste lane (warm, collected, imperfect, anti-AI) and a louder luxury-spectacle lane (marble, ornate ceilings) that wins on raw views but not on credibility.

Trending styles & themes

Trending video formats

How the content is packaged matters as much as the styles. These are the formats carrying the conversation.

    Watch: what the creators are posting

    The actual videos behind the report, ranked by views. Three lanes: spectacle raw-view luxury · vibe wordless cozy · taste designer commentary.

    The library — 26 styles

    26 styles across five tiers — ★ Featured leads with the curated top 7, then Trending, Timeless, Historic, Destination (⛲ Outdoor styles work outside — Bali ① and Ibiza ② lead outdoor editing), and Kids last. Each card shows its aka name, a detailed description, palette, and a live TikTok/IG popularity badge (HotNiche, 30-day reach). Click any card for its rooms, description and real example posts.

    Trending aesthetics — and what we're missing

    I scanned 22 trending interior aesthetics on the same scale as the library, ranked by 30-day TikTok/IG reach. Gap = nothing in the library · Partial = a style overlaps · ✓ Now covered = closed by the additions. Updated after the additions: the big colour and dark gaps are now closed — only 2 true gaps remain, sorted to the top below.

    ✓ Bold colour / dopamine — closed

    Was the #1 hole (~4.8M). Now covered by Dopamine Decor (#3, 3.2M), Heritage Maximalism and Burrowcore. Pink/Barbiecore and Unexpected Red fall under Dopamine.

    ✓ Dark / moody — closed

    Dark Academia (the renamed Colour-Drench Heritage) now owns this — Dark Academia (411K) and Moody Interiors (234K) are covered. Only Whimsigoth's witchy/celestial flavour stays open.

    ✓ Modern Farmhouse — closed

    Now covered by Modern Farmhouse (~616K) — the American modern-barn look (white shiplap, big island, black metal, apron sink), distinct from cottagecore and English Country.

    Remaining true gaps

    Just two now, both small: Whimsigoth (294K, witchy/celestial) and Desert/Southwestern (niche). Cottagecore (4M) and Wabi-Sabi (3.3M) stay partials — big, but covered by English Country / Burrowcore / Japandi.

    What's covered

    The library is strong exactly where the credible designer-taste lane is: warm minimalism, color drenching, Japandi, mid-century, modern Mediterranean and the heritage cluster are all direct hits. The two most-named techniques of the moment — warm-but-imperfect minimalism and color drenching — each have a dedicated style. Kids and destination tiers add product breadth the trend cycle doesn't demand but customers do.

    What's not covered

    The original library was ~80% warm-neutral and missed the loud, colourful counter-current — but those gaps are now filled: Dopamine Decor, Heritage Maximalism and Burrowcore cover bold colour, and Dark Academia covers the moody lane. What remains uncovered is small: Whimsigoth (witchy/celestial) and micro-trend motifs (animal print, checkerboard, cabbagecore, skirted furniture) that are styling tics rather than full styles.

    Why these styles were added

    All eight additions are now live with images. This is the rationale behind each. Full prompts in proposed-styles.json; the complete spec is in STYLE-LIBRARY-CHANGES.md.

    The strategic read

    The designer-taste lane (warm, collected, anti-AI) and the view-farming luxury lane (marble, ornate ceilings) are diverging hard. The library is built for the first - the right call for an Olivia-Bowen / Zara-Home-type audience. But the gap scan shows the library is ~80% warm-neutral and absent from the two loudest trending lanes.

    Recommendations — done this round ✓

    ✓ Done

    Bold colour / Dopamine — added

    The #1 hole (~4.8M) is closed: Dopamine Decor, Heritage Maximalism and Burrowcore are now live styles.

    ✓ Done

    Dark / moody — named

    Colour-Drench Heritage → Dark Academia now captures the Dark Academia + Moody search demand directly. 70s Revival, Brutalism and Bauhaus also added for depth.

    ✓ Done

    "Found Luxury" → "Quiet Luxury"

    Renamed. By its real name it ranks #6 Strong (419K) instead of dead-last — the demand was always there.

    ✓ Done

    Modern Farmhouse + Modern British Eclectic — added

    Modern Farmhouse closes the Modern Farmhouse gap (American modern-barn, ~616K); Modern British Eclectic adds the playful British designer look (Appreciation Project / jack.designs), featured on editorial merit. Both rendered and live.

    Optional niche fills

    Whimsigoth (294K, witchy/celestial) is the last notable gap. Optionally split Cottagecore (4M) / Wabi-Sabi (3.3M) out of their partials if you want them as standalone styles.

    Net: every notable gap is now closed — the library has grown from 18 to 26 styles, including the British designer look and a British-rustic farmhouse. The only true gaps left are Whimsigoth and Desert/Southwestern, both small. Separately, lean renders toward believable and lived-in given the community's vocal anti-AI-render backlash.
